[Elecraft] [K3] Trouble with RTTY

[Roger Marrotte]

I've been fooling around with RTTY for a few days on my K3.  It was working
fine yesterday.  I even made a contact and was told I was loud and clear,
but today I'm having a problem on receive.  The K3 is in DATA mode and set
to FSK D.  It was in this mode yesterday.  I have the DUAL PB turned on.
I'm able to tune in an S9+ RTTY signal easily and have it decode on the K3
screen solidly.  I have MMTTY (latest version) running on my computer.  When
the K3 is in DATA mode (whether DUAL PB is on or off) the audio from the
radio to the computer is virtually nonexistent.  The audio from the K3
speaker is loud and clear.  This is while the K3 is decoding the RTTY
perfectly on it's screen.  I have CWT turned on and the LCD segments are
centered.  FC says * 1.35 and is not movable. If I switch the K3 to LSB, the
audio to the computer is is now loud and decodes perfectly in the MMTTY
screen.  LIN OUT is set to 15 and seems to be more than enough for MMTTY.  I
touch nothing else but the MODE.  This didn't happen yesterday.  Yesterday
while in FSK D DATA mode, the audio to the computer remained loud and clear.
It's almost as if today the K3 isn't putting out audio when it is in FSK D
MODE or that the filter is somehow shifted.
